I don't know. A lot of people say she said things that she really didn't. For example, some of my friends heard something like that that I'm sure is false and now they aren't allowed to have anything to do with Harry Potter. But it would be cool if she wrote another! But it wouldn't have as much intensity without Voldemort...
Well maybe it would be a harry potter book in the future because they already had Harry and everyone grown up already so I think it would be cool if it was a battle againist the little ones
